You will need to rotate the jewels in groups of three. The goal is to get three of the same jewel around the same triangle space. When this happens the jewels will disappear and the triangle space will turn gold. You need to turn all of the triangles in the space to gold in order to complete the level. You have a time limit to complete each of the levels so work quickly. The levels will increase in difficulty as you go along. Also, new things will unlock as you go along such as bombs that will blow up any triangle space you choose.
